Environmental and Genetic Effects on Preweaning Performance of Calves From First-Cross Cows. Ii. Growth Traits

Slaughter and carcass traits of calves from first-cross and reciprocal back-cross beef cows

“…, the maternal performance of crossbred cows (Fredeen et al 1981(Fredeen et al ,1982a(Fredeen et al ,1982bMcKay et al 1990), the efficiency of crossbred cows (Fredeen et al 1987(Fredeen et al , 1988, and the carcass characteristics of crossbred calves (Rahnefeld et al 1983a(Rahnefeld et al ,b,c, 1984. The primary purpose of the research reported here was to compare the slaughter and carcass characteristics ofheifers and steers born to cows representing several European x British F1 and backcross genofypes and one all-British F1 cross (Hereford x Angus).…”

The influence of outliers on a model for the estimation of crossbreeding parameters for weaning weight in a beef cattle herd

“…No distinction was made between Hereford (H) and Aberdeen Angus (AA), as earlier studies (Fredeen et al, 1982;Tosh et al, 1999) did not detect important differences between them. Therefore, both breeds were pooled and considered as one breed (HA).…”

Economics of Calf Production With Foreign Cattle Breed Crosses in the Parkland Region of Western Canada

“…The weights were for male calves, female weights can be obtained from the female to male birth weight ratio. The weights were derived from the data repofied by Fredeen et al (1982b). The calving rate, one minus prenatal calf mortality (Fredeen et al 1982a) For personal use only.…”
